Liquid crystal display panel and a fabricating method thereof that are capable of forming an insulating film exposing a metal pattern without a photolithography process
View Patent ↗A liquid crystal display panel and a fabricating method that forms an insulating film exposing a metal pattern without a photolithography process. The liquid crystal display panel comprises: a metal pattern having first and second surface processing regions having a different reacting property for a specific solution; and an insulating film of a material representing a property identical to that of the second surface processing region, the insulating film being formed on a metal pattern of the second surface processing region in order to expose the first surface processing region of the metal pattern.
1. A method of fabricating a liquid crystal display panel, comprising:
forming a metal pattern;
surface-processing the metal pattern in order to have a first surface processing region and a second surface processing region that have different reacting properties for a specific solution; and
forming without photolithography an insulating film of a material having a reaction property identical to that of the second surface processing region on the metal pattern of the second surface processing region in order to expose the first surface processing region of the metal pattern,
wherein the step of surface-processing the metal pattern includes forming the first surface processing region by irradiating a portion of the second surface processing region with UV (ultraviolet) light.
2. The method according claim 1 , wherein the first surface processing region is a hydrophobic region and the second surface processing region is a hydrophilic region.
3. The method according claim 1 , wherein the insulating film is made of a hydrophilic material.
4. The method according claim 1 , wherein the insulating film includes at least any one of:
a high polymer organic insulating material having a polyvinyl alcohol, a polyvinyl phenol and a novolak resin;
an inorganic insulating material dispersed to a solvent; and
an organic/inorganic hybrid insulating material.
5. A method of fabricating a liquid crystal display panel, comprising:
forming a metal pattern;
surface-processing the metal pattern in order to have a first surface processing region and a second surface processing region that have different reacting properties for a specific solution; and
forming without photolithography an insulating film of a material having a reaction property identical to that of the second surface processing region on the metal pattern of the second surface processing region in order to expose the first surface processing region of the metal pattern;
wherein the step of surface-processing the metal pattern includes forming the first surface processing region by pressuring a pattern mold material on a portion of the second surface processing region.
